QX4 pistol is a relatively new full-size, service type handgun which is manufactured in Chinafor commercial export sales. It is designed to accept .45ACP (11.43x25mm) ammunition, which is most popular in USA, but also can be converted to several other popular calibers, such as .40SW (10x22mm), 9x19mm Luger, and, surprisingly, 7.62x25mm Tokarev.


QX4 pistol is a semi-automatic pistol with polymer frame and double action trigger with exposed hammer. It features delayed blowback action with non-recoiling rotating barrel, broadly based on the concept of the US Savage pistols from early XX century. However, in QX45 spiral grooves are relocated from the slide to the barrel, and made through its entire length, providing additional braking force.  Braking grooves have different spiral pitch for each caliber. Due to different diameters of the various cartridges, QX4 pistol features removable breechblock system; therefore, caliber change involves disassembly of the gun, and replacement of the barrel, breechblock and use of appropriate magazines. Manual safety is located on both sides of the frame. Gun is fed using double-stack magazines with 12 rounds capacity in .45ACP, and bigger capacities in smaller calibers.
